To all whom it may concern;

Be it known that l, GILBERT F. Henson, a subject of the King of GreatBritain, but having declared my intentions of becoming a citizen of theUnited States, residing at.

the borough of Richmond, in the county of Richmond, city and State ofNew York, have invented an Improvement in Wrapping-Machines, of whichthe following is a specification.

My invention relates to machines for placing wrappers upon bottles,cans, or other No. 151,397, filed by me February 28, 1917,

which relates to the mechanism for feeding the wrappers to the bed ofthemachine in the path of the wrapping block described and claimed herein.

In the same machine 1 make use of mechanism for feeding the bottles orother cylindricalarticles to the machine and elevating them one at atime to the bed of the machine adjacent the wrapper deposited thereon bythe mechanism forming the subject matter of my said application SerialNo. 151,397, which bottle feeding and elevating mechanism forms thesubject matter of still an other division of my said ap lication SerialNo. 151,397 which other divisional application was filed Aug. 9,1917,under Serial No. 185,276.

ity of uprights such as 10 and 11, the top being stepped, forming a mainbed 12, extending longitudinally the full length of the frame at itsfront, and a lower bed 13, at the rear, upon which are supported a pasteor glue box 11, and a feed box or holder 15, for the wrappers.

16, indicates the main shaft which is j our-- naled at its respectiveends in crossbeams 17.

18, designates the motor, upon the shaft 19, on which is secured a gear20, meshing with gear 21, fixed to a shaft 22, journaled in bearings ina bracket 23 fixed to the frame at the front of the machine in line withthe main shaft.

Fixed to the shaft 22, at one side of the gear 21, is a pulley 21. 25,indicates a pulley fixed to. the main shaft 16, adjacent one end. 26,denotes the drive belt which passes around the pulleys 21 and 25.

The wrappers, one at a time, in rapid suc' cession are glued along twoor more edges, taken from the holder 15, and deposited upon the main bed12, by the wrapper carrier 27,

and connected release plate 28, constructed and operated by mechanismdescribed and illustrated in my said application Serial No. 151,397.

There is an opening 29, in the main bed 12, adjacent the place at whichthe wrappers are deposited by said carrier and release plate.

-11 plurality of bottles 30, which are to be covered by the wrappers,are arranged in a row within a feed chute 31, the bottles being placedupon their sides, bottoms foremost, the top of one bottle contactingwith the bottom of the next bottle. The bottles are pushed toward theopen end of the chute 31 under the bed 12,.the length of one bottle at atime by the pusher 32 operated by a cam 33 keyed to the main shaft 16,which acts upon a roller 34' attached to an arm 35, one end of which isbifurcated and straddles the main shaft, the other end of the arm beingupon a bed 10, which is secured to a block 11,

and to this block the upper end of an arm 42, is pivotally connected.The lower end of said arm is bifurcated and straddles the main shaft. Aroller 13, attached to one side of said arm is acted upon by a cam L4keyed to the main shaft whereby the block and bed are raised into theopening 29 in the bed 12 of the machine. This bottle. feeding and ele-'vating mechanism forms the subject matter of my other divisionalapplication above referred to, filed August 9, 1917, under Serial No.185,276.

A bottle reaches the top of the main bed 12 just as a glued wrapper hasbeen deposited upon the bed in front of the opening 29 by the wrappercarrier 27 and release plate 28 fullydescribed and illustrated in mysaid application Serial No. 151,397.

45, indicates a vertical shaft journaled at its lower end in a bracket46, its upper end passing through and journaled in a bearing 47, in anextension of the frame of the bed 13. Keyed to the upper projecting endof the shaft 45 is a horizontal gear 48. 49, is another horizontal gearkeyed to the lower end of the shaft 45 and meshing with a gear 50 keyedto the main shaft 16.

51, is a short vertical shaft passing through an opening in the bedframe 13, and bearing 52, its lower end being threaded upon which isscrewed a nut 53. Upon the upper end of the vertical shaft 51 there iskeyed a ear 54 meshing with the gear 48 on the sha t 45.

55, designates a vertical shaft the lower end of which is journaled inthe cross beam 38, its upper end passing through an opening in the bed12, there being a bearing 56 for this shaft secured upon the under sideof the bed 12.

A gear 57 is secured upon the shaft 55 which gear meshes with the gear54 on the shaft 51. By this gear connection it will be seen that theshaft 55 is continuously revolved while the main shaft is rotating.

58 indicates a .hub keyed to the upper end of the shaft 55 from theupper end of which hub projects two horizontal arms 59 and 60, the freeends of which are spaced apart a predetermined distance, there being across brace 61 between the two arms, and side braces 62 and 63 extendingfrom the lower part of the hub 58 and connecting with the arms 59 and 60respectively at a predetermined distance from their free ends.

The hub 58, arms 59, and 60, cross brace 61, and side braces 62 and 63,are preferably cast in one piece of metal.

64, indicates the rapping-block which is curved longitudinally andpreferably covered on its under surface with soft material or a pad 65.

66 and 67, indicate two hangers, the lower ends of which are pivotallyconnected to the wrapper-block, one at each side thereof adjacent oneend, The upper ends of these hangers are pivotally connected to the freeend of the arm 59, by a bolt 68.

Each of these hangers is preferably composed of two rods provided withright and left screw threads respectively upon which is screwed aturnbuckle or threaded sleeve 69, by means of which the height of thewrapping-block above the pad 73 on the bed 12 may be adjusted.

70 and 71, indicate another pair of hangers similar to the hangers 66and 67. 72, is an angle piece which is secured to the end of the arm 60by a bolt 74, which bolt also pivotally connects the upper ends of thehangers 70 and 71 to the end of the arm 60. A lug 75 provided with ahole is secured to the top of the wrapper-block 64: and the lower end ofthe hanger 70 is pivotally secured thereto by a bolt. The opening in thebottom of the hanger 70 for the passage of said bolt is elongatedsomewhat vertically to allow a certain amount of vertical movement tothat end of the wrapper-block which is controlled by a spiral spring 76which surrounds a vertical pin 77 secured at its lower end to the top ofthe wrapper-block, its upper end extending through a hole in theangle-piece 72, the spring 76 bearing at its top against the undersurface of the angle-piece and at its bottom against the top of thewrapper-block.

78 and 79, denote two connecting devices between the respective sidebraces 62 and 63, and the wrapping-block 61. These connections areconstruct-ed similar to the hangers 66 and 67; that is, they are eachformed of two sections of rod provided with right and left threadsrespectively upon which are screwed turnbuckles or right and leftinteriorly threaded sleeves 80.

One end of the connection 78 is pivotally connected to thewrapping-block, the other end bein pivotally connected to the outer sideof the brace 62. The connection '79 is connected at one end pivotally tothe lug 75. upon the top of the wrapper-block and its other end ispivotally connected to the outer side of the brace 63. These connections78 and 79 provide means for adjusting and holding the wrapper-block inan inclined relation to the bed 12 when so desired and as shown,although it will be seen that the wrapping-block may be positioned sothat itsdbottom surface will be parallel with the b Upon the rear end ofthe wrappingblock 64 and secured thereto is a vertical cross-piece 81,one end of which extends a predetermined distance beyond the inner sideof the wrapping-block.

82 and 83 are two gripper arms pivotally connected to the inner side ofthe crosspiece 81.

The arm 83 is pivoted at 84 and extends along the inner surface of thecross-piece menace beyond each end thereof. that end at the outer end ofthe cross-piece being bent downwardly at right angles adjacent the outerside of the wrapping-block 64:.

The arm 82 is pivoted at a point on the cross-piece lower than the pivot84, and extends from that point along the inner surface of thecross-piece and beyond its inner end. Adjacent its pivotal connectionthis arm 82 is bent downwardly at right angles adjacent the inner sideof the wrappingblock. Upon the inner sides of each of the.

downwardly bent portions of the arms 82 and 83 and at the ends thereof,is secured a pad 85 by any suitable means. T have shown rivets 86 forthis purpose.

The inner'ends of the arms 82 and 88 are enlarged in thickness and upontheir opposite surfaces are each provided with a socket 87, in each ofwhich is positioned an elongated roller 88 provided with trunnions 89having bearings at the opposite ends of said of folding fingers extendonly a predeter-v mined distance along the rear end of thewrapping-block.

93, denotes a semi-circular spreader-rail supported a predetermineddistance above the bed 12 by vertical posts 94, secured at their upperends to the rail and at their lower ends to the top of the bed 12. Theends of this rail are beveled.

The vertical shaft 55, being continuously revolved by the mechanismheretofore described so long as the main shaft 16 is being driven by themotor 18, the wrappingblock is continuously carried in a circle over thebed 12 at an adjusted height above the same, and when its forward end,which is preferably curved slightly upwardly, comes in contact with theperiphery of a bottle which has been raised by the elevating moansbefore referred to to the top of the bed 12, it rolls the bottle forwardover the gummed wrapper (which has been deposited upon the pad 73 by themeans and in the manner hereinbefore referred to,) and in so doing thewrapper is rolled around the bottle and secured thereto by its gummededge longitudinally of the bottle; this is accomplished instantaneouslyand before the bottle reaches the folding fingers 91, but in passingthese folding fingers that portion of the rolled wrapper extending fromeach end of the wrapped bottle is turned over and down upon the top andbottom of the bottle by suchfolding fingers. When past the row offolding fingers the bottle has been rolled into a position between thegripper arms 82 and 83 at either side of the block 64, and the movementof the wrapperblock is so timed that at this moment the inner horizontalends of the gripper arms have reached one end of the spreader rail 93,which passes between the rollers 88 in the gripper arms spreading themapart and throwing their padded ends toward each other and against thetop and bottom of the wrapped bottle thus gripping the same betweenthem, (see Fig. 4), and carrying it forward until the rollers 88 pass 0dthe rail 93 at its other end when the arms 82 and 83 are drawn back totheir normal position by the contracting of the spring 90.

When the wrapped bottle is released from the gripper arms it dropsthrough an opening 95 in the bed 12, and into a curved inclined chute 96arranged under the bed 12 at this point, and from the chute 96 thewrapped bottle is deposited in an upright position upon a conveyer band97. A guide piece 98 is arranged at the lower open end of the chute 96to set the wrapped bottles upright as they are delivered from the, chuteand upon the conveyer.

I prefer to provide a stop 99 at the forward end of the opening 95 inthe bed to prevent any possibility of any of the wrapped bottles passingor striking the edge of the opening.

The movements of the respective parts are so timed that a gummed wrapperwill be deposited upon the pad of the bed, and a bottle elevated to thelevel of the bed so as to be in the path of the wrapping block at eachrevolution of the same. The machine is operated with accuracy andrapidity, and is: adjustable to varying sizes and styles of cylindricalarticles.

A semi-circular shield 100, is preferably provided for the protection ofthe operator against contact with the moving parts over the bed, and Talso prefer to employ a cover- 15 ing 101, for that part of the machinebelow the bed.
